  2. 16. Thermal Barrier Coatings : Failure Mechanisms and Life Prediction

    Author : Krishna Praveen Jonnalagadda; Ru Lin Peng; Xin-Hai Li; Robert Eriksson; Nicholls John; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Thermal barrier coatings (TBCs) use in the hot sections of gas turbine engine enables them to run at higher temperatures, and as a consequence, achieve higher thermal efficiency. For full operational exploitation of TBCs, understanding their failure and knowing the service life is essential. READ MORE

  4. 17. Thermal response test : method development and evaluation

    Author : Signhild Gehlin; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Abstract : Since the first introduction of thermal response tests with mobile measurement devices in Sweden and USA in 1995, the method has developed and spread in North America and Europe. Thermal response tests have so far been used primarily for in situ determination of design data for BHE (borehole heat exchanger) systems, but also for evaluation of grout material, heat exchanger types and groundwater effects.

  5. 18. Study of the Apparent Kinetics of Biomass Gasification Using High-Temperature Steam

    Author : Aliaksandr Alevanau; Weihong Yang; Wlodzimierz Blasiak; Anna Ponzio; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high temperature gasification; random pore model; grain model; volumetric model; TGA; Thermal energy engineering; Termisk energiteknik; SRA - Energy; SRA - Energi;

    Abstract : Among the latest achievements in gasification technology, one may list the development of a method to preheat gasification agents using switched ceramic honey combs. The best output from this technology is achieved with use of water steam as a gasification agent, which is heated up to 1600 °C. READ MORE

  6. 19. Thermal stresses in load-bearing glass-timber components

    Author : Karin Lundstedt; Erik Serrano; Ola Dahlblom; Linnéuniversitetet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Thermal stresses; thermal failure; glass and wood construction; incident solar radiation; shading; cracks; temperature difference; finite element method.; Technology byts ev till Engineering ; Teknik;

    Abstract : Thermal stresses can arise in glass used in architectonic realisations in buildings as a result of solar irradiation:  that is, sunlight.  The magnitude of these thermal stresses depends on the temperature conditions in the glass in terms of the temperature differences between warm and cold areas.

  7. 20. Modelling and Simulation of Thermal Radiation in Biomass Combustion

    Author : Thomas Nilsson; Förbränningsfysik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat load; gas turbine; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik; porous media; fixed bed; biomass; wood; FG-DVC; combustion; DOM; P1-approximation; Mie theory; RDG-PFA; EWBM; thermal radiation; soot;

    Abstract : This thesis presents numerical investigations and simulations of fixed bed combustion of wood, models for predicting thermal radiative properties of particles and gases related to the combustion of wood, and a review of heat load calculations in gas turbines. All subjects have a common factor in thermal radiation. READ MORE
